Working Principles

SN74LS652DWRG4 operates by receiving address inputs and control signals to perform data bus multiplexing and demultiplexing functions. The address inputs are decoded internally to select the appropriate group of bidirectional data pins. The selected group is enabled, allowing data to be transferred between the IC and the connected devices. The output enable signal (OE) controls the direction of data flow, enabling or disabling the bidirectional data bus.
